FOUNTAIN-BRUSH.

Specification of Letters Patent No.

To all whom it may concern: f

Be it known that I, L. B. Horr, of the city, county, and State of New York, have invented a new and Improved h/Iarking- Brush; and I do hereby declare that the following is a full, clear, and eXact description 0f the same, reference being had to the specification, in which Figure l represents a vertical central section of my invention. F ig. 2 is a horizontal section of the same, the line zo, m, Fig. l, indicating the plane of section.

Similar letters of reference indicate 00% responding parts in the two figures. 2,/

rlhis invention relates to that class of marking brushes in which the marking ink is supplied to the brush from a cistern to which the brush is connected by suitable tubes and passages, and the invention consists in arranging the passage leading from/ the cistern to the brush, in a screw which, screws into the lower part of the cistern, and in such relation to a stationary valve which is rigidly attached to the sides of the cistern, that by turning the screw the flow of the ink is regulated, and that the flow is entirely stopped if the screw be turned in far enough so that the valve comes in contact with the upper end of the passage, the valve being of such size and in such a position that it stops the passage up if the screw be turned to the proper distance; and the invention further consists in fastening the brush on the outside of a conical tube which forms a passage for marking ink to the brush, and which fits into a conical shell so that the-hairs are further secured by pushing the tube down the shell.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, is a cistern constructed of sheet brass, tin or any other suitable material and closed at the top by a` cover B. Its lower and narrower end is open anditis strengthened by inserting a bushing C, into which a screw thread is cut, and a screw D, screws up into this bushing. This screw has a central passage a, and a cross bar Z, is rigidly attached to the sides of the cistern to which a projection C, is attached which fits into the upper part or end of the passage a, and which serves as a valve to stop or regu- 23,028, dated February 22, 18591 The lower end of the screw D, is tapering and a conical shell E, is placed over it, and this shell contains the brush F, which is attached to a conical tube G, the hairs being attached to the lower end of the same by some suitable cement. The bevel of t-he tube G, is the same as that of the shell E, and the two are of such relative size that by pushing the tube G, down into the shell E, the hairs are cramped between the outside of the first and the inside of the latter, and the brush is thereby made more permanent. At the same time the tube G, forms an outlet pfor the ink which runs down from the cistern through the passage a, in the screw D.

Nhen not used the brush is protected by an additional shell H, which tits over the shell E, and which is provided with a bottom f, so as to protect the brush.

The operation is as follows: Ink is intro- /duced into the cistern by turning the same .upside down and by taking out the screw D, and the cistern is closed perfectly air tight if the screw D, be inserted and screwed up far enough so that the valve o, closes the passage a. In order to use the brush, the passage a, is opened, and the flow of the ink regulated to suit circumstances by turning the screw D, more or less, and the ink runs down through the passage o, and through the tube G, to the brush.

I am well aware that self-supplying marking brushes very similar to mine have heretofore been constructed, but none of them to the best of my knowledge and belief ever showed the same arrangement of a stationary valve in combination with the same construction of the brush; I do not therefore claim solely the arrangement of the valve for regulating the flow of the ink, neither do I claim supplying the ink to the brush through the hollow shank of the latter, but

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, as a new article of manufacture, is,

A. marking brush consisting of a cistern A, which is provided with a stationary valve c, and having the brush attached to a conical tube G, which fits into a shell E, and otherwise constructed substantially as herein described.
